An overview of the measurements of most important beam
parameters in heavy ion machines is given. The special
characteristics of heavy ions concerning the great variety
of parameters with respect to the type of accelerator (linac,
circular machine), the species of accelerated ions as well
as their energy, beam intensity, beam emittance and time
structure are considered. The consequences for the design
of beam diagnostic systems are discussed. Typical examples
of measuring systems are given. Experimental results
taken during the long operating time of the GSI facilities,
covering a wide range of parameters, are reported.

For the commissioning of the new GSI prestripper a conventional
slitdetector system and a single shot pepperpot system has been
installed on a mobile test bench to measure intensity distributions in
the two transverse phase spaces. To determine intensity distributions
in the longitudinal phase space, including beam energy capacitive
pickups and newly developed diamond counters have been installed on the
test bench. The setup of the test bench provides also redundant
information for beam current, beam profile and beam position. The most
important features of all measuring systems including signal processing
and data evaluation are reported. First results from the commissioning
of the upgraded prestripper of the UNILAC at GSI are reported.

The complex mathematical algorithms and procedures
to extract emittance data from intensity distributions
measured with a single shot pepper-pot device are
described. First results of mathematical evaluation from
the commissioning of the new GSI pre-stripper linac
structures are presented.

For the characterisation of the ion beam delivered by
the new High Current LINAC at GSI, the time structure
of bunches and the knowledge concerning their intensity
distribution in longitudinal phase space is of great
importance. At least 100ps time resolution and the
capability of measuring long tails in the distribution were
design parameters. Taking advantage of Rutherford-scattering
to reduce the count rate, a direct time of flight
measurement technique using diamond detectors can be
applied. First results are reported. Plans for determine the
energy of individual ions by detecting secondary
electrons emitted from a thin C foil using 1m drift are
discussed.
